    "abstract": "Recent experiments on similarly shaped polymer micro-cavity lasers show a\ndramatic difference in the far-field emission patterns. We show for different\ndeformations of the ellipse, quadrupole and hexadecapole that the large\ndifferences in the far-field emission patterns is explained by the differing\nray dynamics corresponding to each shape. Analyzing the differences in the\nappropriate phase space for ray motion, it is shown that the differing\ngeometries of the unstable manifolds of periodic orbits are the decisive\nfactors in determining the far-field pattern. Surprisingly, we find that\nstrongly chaotic ray dynamics is compatible with highly directional emission in\nthe far-field.",
